SPECIFICATION forming part of Letters Patent No. 651,536, dated June 12, 1 900.

Application filed August 2, 1899- Serial No. 725,346. (No specimens.)

To all whom it may concern; Be it known that I, HERMAN STERN, a residentoi Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new 5 and useful Improvements in Cleansing Compounds; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make to and use the same.

:5 This compound results from the mixing of oxalic acid, ammonia, bicarbonate of soda, borax, turpentine, permanganate of potash,

The proportions suitable for ordinary work are about six ounces of a nzo monia, six ounces of borax, three ounces of tur )entine, six ounce??? oxalic acid, six ofine0f bicarbo of soda and lomunccs of permanganate of potash to about one gallon of waiefluflh' p'roportions will vary 25 according'to the nature or character of the goods that require cleaning and according to the nature and character and quantity of the dirt that is to be removed. The use of hot water is preferable to cold water, and ammonia of medium or greater strength is preferable.

The compound is applied to the goods by thoroughlyscrubbing them with a brush, becomes saturated with the dirt, and is then scraped oil in any approved manner, and thereupon the goods are sponged with warm water, which completes the cleaning opera tion.

The use of permanganate of potash is important for the purpose of softening the solution and brightening the goods, and, furthermore, when permanganate of potash is used either hard or soft water can be used; but of course more permanganate of potash is used with hard water than with soft water.

\Vhat I claim is The cleansing compound herein described, resulting from the mixing of oxalic acid, ammonia, bicarbonate of soda, borax, turpentine, permanganate of potash and water.

Signed by me at Cleveland, Ohio, this 27th day of July, 1899.

HERMAN STERN.
